EM scattering by conductor plate coated with multilayered medium having metamaterials

The electromagnetic scattering of conductor plate coated with multilayer medium is investigated based on the physical optics (PO) theory and the principle of equivalent impedance boundary condition (IBC). Compared with the multilayered plate coated with right-handed medium, the radar cross section (RCS) of plate composed of metamaterial and right-handed medium has a reduction of 5.76dBsm in the mirror direction. It shows that metamaterials can become a candidate of the radar absorbing material (RAM), which offers a new idea for the development of stealth technology.
